Machine tool characteristics

1. This machine tool is made of advanced Mihanna cast iron and box structure design and manufacture, after proper annealing treatment, eliminate internal stress, tough material, coupled with box structure design, high rigid body structure, so that the machine has enough rigidity and strength, the whole machine shows heavy cutting ability and high reproduction precision characteristics. The beam is a stepped lifting system, with a highly user-friendly operational design, which can maximize the heavy cutting capacity. The beam moving clamping and loosening device is hydraulic loosening and hydraulic clamping.

2. Z-axis square rail uses a large cross-sectional area (250×250mm) to improve cutting capacity and ensure high cylindricity. The slide column is made of alloy steel through annealing.

3. High precision, high rigidity spindle head, the machine adopts FANUC high horsepower spindle servo motor (power up to 60/75KW).

4. The main shaft bearings are selected from the United States “TIMKEN” CROSS ROLLER or European “PSL” cross roller bearings, with an inner diameter of φ901 large bearing aperture, providing super axial and radial heavy load. This bearing can ensure long time heavy cutting, excellent accuracy, stability, low friction good heat dissipation and strong spindle support, suitable for large workpieces and asymmetric workpieces processing.

5. Transmission characteristics:

1) No noise and heat transfer to the spindle.
2) No vibration transmission to the spindle to ensure cutting quality.
3) Transmission and spindle separation lubrication system.
4) High transmission efficiency (over 95%).
5) The shift system is controlled by the gear fork, and the shift is stable.

6. Cross-type roller bearing characteristics:

1) Double row cross roller occupies only one row roller space, but its application point is not reduced.
2) Occupy small space, low bed height, easy to operate.
3) Low center of gravity, small centrifugal force.
4) Using Teflon as the bearing retainer, the inertia is small, and it can be operated at low torque.
5) Uniform heat conduction, low wear, long life.
6) High rigidity, high precision, vibration resistance, easy lubrication.

7. X/Z axis adopts FANUC AC prolonging motor and large diameter ball screw (precision C3, pre-pull mode, can eliminate thermal expansion, improve rigidity) direct transmission, no belt drive accumulated error, repetition and positioning accuracy. High precision angular ball bearings are used for support.

8. ATC knife library: The automatic tool changing mechanism is adopted, and the capacity of the knife library is 12. Shank type 7/24taper BT-50, single tool maximum weight 50kg, tool library maximum load 600 kg, built-in cutting water device, can really cool the blade life, thereby reducing processing costs.

9. Electrical box: The electrical box is equipped with air conditioner to effectively reduce the internal ambient temperature of the electrical box and ensure the stability of the system. The external wiring part has a protective snake tube, which can withstand heat, oil and water.

10. Lubrication system: The machine automatic depressurized lubrication system collection of oil, with advanced depressurized intermittent oil supply system, with timing, quantitative, constant pressure, each way to provide timely and appropriate amount of oil to each lubrication point, to ensure that each lubrication position does get lubricating oil, so that the mechanical long-term operation without worries.

11. X/ Z axis is a symmetric box-type hard rail sliding table. After heat treatment, the sliding surface is combined with a wear plate (Turcite-B) to form a precision sliding table group with high precision and low friction.
